METHOD OF AND MEANS FOR PRODUCING DESIGNATIONS ON PHOTOGRAPHICALLY- SENSITIVE ELEMENTS.

Application filed April 14, 1913.

The'object of any invention is to provide an improved method of produciug'auy dcsircd-dc5signationsupon light sensitive elements, such as'pliotogi'aphic film, which is ada ited to be contained in a holder or camera. y altering the light transmitting properties of a' covering therefor in the desired characters and then light printing, such designations u on such element.

A further 0 ject of my invention is to provide a, sensitized element for photo graphic purposes-such as a flexible sensitized film, having an opaque cover or protector associated therewith to exclude the passage of light therethrough before exposure, such cover, being, however, of such a. nature as to permit it or a portion thereof to be displaced. as by'writing designations u on or against the same while upon said cement, to enable such designation to be photographed upon the sensitive surface of said element when such designation is exposed to light, without requiring the element to be exposed througha lens for the purpose of photographing the designation on the element.

In carrying out my invention I provide a photographically sensitive element, such as an ordinary photographic flexible film, and upon oragainst the same I place an'opaque covering sheet or strip, having a body, surface or coating that is more or less readily or freely displaceable, such as a sheet of :translucid paper upon at least one surface of which is an'opaque displaceable substance. For this purpose I find that a sheet of siptable carbon transfer paper accomplishes lhe purposes, whereby a designation, such as a name, date, initial or the like, may be wr tten or marked upon, or a ainst, such displaceable surface of such film cover before the film is exposed, and then the displaced portion of said cover may be exposed with- Specification of Letters Patent.

out the use of a lens to affect the sensitive surface of said filin oppositc'such designation, to photograph on the film the designation made upon such cover. Exposure of the film to take a picture may be made in the ordinary way after the designation has been photographed thereon and then the film may be developed and printed as usual, producing a. print having the desired designation thereon. displaceable surface on the translucid sheet asof the nature of the opaquecoatingusually employed upon carbon or transfer 'papers,'it will be understood that my invention is not limited thereto, since cover may be such that while being opaque it may'itself be more or less readily or'freely cut into or displaced where the designation is produced-thereon, affording thereby means for the passage of light through such desig n'ation to the film. By preference, I con;

the nature of the film transported and handled, while. serving as a medium to permit a desi nation, when desired, to be manually produced against the film for photographing thereon without affecting the remainder of the film. \iVith films, of the roll-up variety, 1-; preferably Iprovide the opaque cover so that it extends ieyond one end of the film, andconnect the two to ether by some suitable adhesive ma terial adjacent to the end or endspf the film, although, of course, the film may be more or less coextensive in' length with said protect ing means. i i

The nature and uses of my invention will be more fully hereinafter set forth and then point-ed out in the claims.

Reference isto be had to the accompanying drawings formin part hereof, wherein,

Figure 1 is a partly sectional view of a flexible film equipped with 'my invention, shown adapted to roll on a spool in the ordinary manner, illustrating one form of carrying out my invention, wherein the displaceable surface of the opaque .film cover is exposed on the exterior surface, and the sensitized surface of the film is opposed to the protecting moans; a

Fig. 2 is a similar view illustrating the '25 when in a camera .or wpund marked or written u 335 light to'strike thereon of desired desi ations film material or celluloid opposed to the. protecting means, and the sensitized surface of the filmon the side opposite said means;

Fig. 3 illustrates the film and its sensi- 5 tized surface as in Fig. 2 covered by two layers of flexible cover, and

Figs. 4, 5 and 6 are detail sectional views on the lines 4, 4, 5, 5, and 6, 6, in Figs. 1, '2 and 3 respectively.

Fig. 7 is a sectional view of a modification. Similar numerals of reference indicate corresponding parts in the several views.

The sensitized element, such as the flexible film 1 havin the sensitive surface 2, may

15 be of any we -1 knownform, and, as shown in Figs; 1, 2, 3, is adapted to be wound upon a spool, support,or the like 3. My improved film cover adapted to have its surface or a portion thereof displaced'for the production is indicated at 6, in the nature of a exible-slieet or strip, and laced against'or upon the exterior of the the nature of such cover being such as to normally exclude light from the film, on a support,

such coyer'eithe'r having material applied L the translucid paper 6. The protecting cover ,celluloid 1 laid against the paper 6 duced thereon will thus lieseiigainst the film to normally exclude light th efrom, and in the form shown in FigsL and 3'the opa ue strip 6 is secured ad acent to one end ofe film and adapted wound u on the spool with the film. The materia 7 may be disposed e'xteriorly of the film, with the sensitized mate 'al of the film laid against'the translucid p per 6, as in Fig. 1, or with the film mate ml or I d the sensitized surface 2'on the opposite .side of film 1, as in Fi 2. This arrangement of Fig. 1 protects t e film or its sensitized surface from contact with the opaque readily displaceable material 7 of the protecting cover, to avoid smearing or affecting the film or its sensitized surface, and with such material 7 exposed directly to the action of a'pcn- .cil or the like, the marking or writing prodis lace the corresponding portion of such cisplaceable material,

' permitting. the light to strike therethrough to the sensitized film, the remaining or lin written port on of the cover excluding light from such film.

In the form shown in Fig. 3 the cover 6, 7, may in turn be covered by another flexible cover 6, which may have the displaceable surface 7 placed against the corres onding material 7 of the inner cover. As s own in Fig. 7, the outer cover 6 need not have the material 7 thereon and in this construction the displaceable material 7 is applied-to a translucid strip 6', is rovided with the sensitive emulsion 2.

hese arrangements keep material 7 or 7" from engaging any pa film when wound together on the s yet by marking or writin of the outer translucid sieet 6 or 6",

t of the l, and

the

material 7 or 7" thereunder will be displaced when the designation is produced thereon to enable the light to strike through such marked or written portion to affect the film for photographing the designation thereon when ex osed to light.

It wil be understood that my improve ments may be used in cameras or photographic apparatus in the ordinary manner of inserting, operating and removing the films, provision being made, however, in the camera, to enable access to at least ii portion of the cover on thefilnifor marking or writthe displaceableand the celluloid strip 1" upon .the surfaoe ing against. the coverwhile faceto face in the camera, any suitable support within the camera opposed to the portion of the inate ponbeing provided to enrial to be written able the designations to be properly prodncedthereon. In the 'form s own in Ii s.

'1, 2 and B, the light may strike through t m cover to the fihn,- as the writing onthe cover progresses, exposure directly to the light thereby being permitted for any %e ired inanperiod of time to afiect the filinin suc ner as to photograph thereon only such designation through tl16 --mh}k(l or writtennpon portion of t h'ei opaque. cover, after which the film magi be exposed to take the picture in the. 01 na-ry manner, *the film -thereafter to be developed and printed as' usual. Or, the film may first be exposed in a usual way to take. a picture and then the designation may be produced on the film in the manner before described, -suitalileieiiposure of such designation being permitted to cause the designation to be produced by the light upon the film, after wh ch it willbe developed and printing therefrom may be done as usual.

My invention afi'ords a simple and inexpensive opaque cover for iaving the inherent capacity to enable a film to be plioto raphically niarkcdor designated at will, without resort to the darkroom for the purpose, since the desired designation may be written ormarked upon the opaque ilisplaceable cover that is on. the film at any time before or after the film is exposed to the lens without permitting the film opposite the unmarked portion of the cover to photographic-film's be affected by the light. By this means any picture taken or to he taken uuay be photographically marked i'vlicrever the exposure is to be made in the usual way but without regard thereto.

I do not in this application claim a camera having means to permit writing upon or against the sensitized element or the protecting means or cover thereon, but my invention relates to providing a sensitized film with an opaque cover enabling designations to be produced thereon or therein while op: posed to and concealing the film, regardless of the particular formof camera in which my invention may be utilized. In this application I use the term translucid as meaning transparent ortranslucent, as distinguished from opaque, although the opaque matcrial covers the translucid material so that when the opaque material is displaced the'lightwill strike through the translucid material to the film.

By the term opaque I mean a film-protecting cover adapted to prevent rays of light from injuriously afi'ecting the seusi tized surface of the film. whether the cover be absolutely impervious to light or' of the well known ruby or other color. which, while not absolutely-opaque, yet itself ermits only such ortion of the light to reac the film as woul not affect its sensitized surface.

While the pressure of ;the stylus may transfer some of the carbon coating to one of the sheets of the covering paper, which might serve to slightly obstruct the passage of light, nevertheless the dis lacement of the opaque carbon coating is $11 cicnt to permit the passage of light to the sensitive emulsion to enable the characters traced by the' stylus to be light printed upon it.
